right now, i'm working on pasting audio files to the video after cleaning some audio files to get the sound much leavel.
Can you compress the size of a 4K Video.

Can you compress the size of a 4K Video.

Most video file already have some compression, I suppose you can re-compress even more, but there will be consequences in sample quality. More compression means the unpacking will be slower (to the point that some systems will not be able to handle this speed) and in the encode there will be losses in quality. Check out the program Handbrake Supplemental tools (wiki)

THe video files never been compressed. every time that i get a dvd of a movie/ tv show, a go ahead and rip it to the computer. So they aren't compress, just rip and stored in 720x480 on a external desktop drive. just had the thought of looking in on 4K and then compressed the size without losing quality.

Zeros & ones would be absolutely enormous on a disk, Moving Picture Experts Group (MPEG) establishes the standards for compressing moving pictures and as such most DVD's are encoded Mpeg-2, previously cd videos used earlier motion jpeg or avi versions, then we jumped to Mpeg-4 h264 encodes, and lately h265, while the newer AV1 is Open and royalty-free video coding format. there is no official standard for what compression rate must be used, and as advancements in coding, storage and hardware speeds, new algorithms will be used. Explaining all of this is best handled with that video link "Explaining Image File Formats".

Handbrake those disks rips will likely give you 75% on a Mpeg-2 -> Mpeg-h264 & more without any appreciable losses, going to h265 will further reduce the files, but the CPU is intensive and takes much more time to re-encode ,using Handbrake (note there is batch features). I once was given a season of a TV Show on a disk set of four, ripping them down to 1 disk was easy with more modern encodes.

OTH: 4K UHD disk files are already using modern encodes, sometimes double sided dual and even 4 layer disks 50-100 gig disks. Throw out the languages you don't need and the audio versions only you want along with the various menu/trailers/ads you might get down to a file size of 25/30 gigs and I'm unsure if further compression without loss is possible.
